A. Application:
1. The submitted Residuals Source Certification Attachment form (RSCA 070807) is an old version of the
current Residuals Source Certification form (RSC 06-16). The 15A NCAC 02T rules that govern
residuals management programs in the non -discharge branch has been updates. The Permittee shall
resubmit the residuals source certifications for both the Town of Ramseur water treatment plant (WTP)
and wastewater treatment plant (WWTP) on the most current RSC 06-16 form.
Noted. See attached correct RSC 06-16 forms for both the Town of Ramseur WTP and WWTP.
The Residual Source Facility Summary is also included.
The Nutrient/Micronutrient Determination (section 11.5 on page 4 of 5 of the RSC 06-16 form) is required
for all residuals sources on all residuals permits for renewal. The Permittee shall submit a fully
completed Section 11.5 of the RSC 06-16 form for both the WTP and WWTP residuals along with the
associated laboratory analytical reports and calculations.
Noted. The Town currently does not have sampling data to complete the referenced section at
this time. The existing permit W00010528 (July 24, 2017) does not stipulate the testing of the
required nutrients/micronutrients required to complete section 11.5 of the RSC 06-16 form per
Condition IV.3 and Attachment A of the permit. The Town recognizes this request regarding this
item and is planning to sample for these parameters during the week of February 17, 2020.
Results are expected by mid -March. Please advise how these results should be submitted to
your office for review.
The vector attractions reduction (VAR) determination in section 11.8 of the Town of Ramseur WWTP's
RSCA 070807 form has been crossed out. However, a VAR options must be selected for biological
residuals unless they are covered at the end of each operating day with a Division -approved soil. It
appears from the submitted data that the residuals meet Alternative 6 - Alkaline Stabilization. The
Permittee shall include this option when the revised RSC 06-16 form is submitted for the Town of
Ramseur WWTP.
Noted and corrected to include VAR alternative 6. The facility does achieve Class B biosolids via
lime stabilization prior to the disposal into the unit.
B. Operation and Maintenance Plan [15ANCAC 02T .1110(a)l:
1. The description of the operational functions submitted Operation and Maintenance (O&M) Plan does not
fit all of the criteria listed in 15A NCAC 02T .1110(a)(1). This rule states that the O&M plan shall:
a. Describe the operation of the program and all associated facilities and equipment in sufficient detail
to show what operations are necessary for the program to function and by whom the functions are
to be conducted. Noted. See attached O&M Plan
The O&M plan shall be revised to more specifically describe all operational functions of the program
and by whom the functions are performed. Noted. See attached revised O&M Plan
2. The Spill Prevention and Response Plan submitted only details response procedures for a spill of the
WTP residuals. A revised plan shall be submitted to also include spill control provisions in case of a spill
for the WWTP residuals as well. Noted. See attached O&M Plan
3. The Spill Prevention and Response Plan submitted have an old contact number for the Winston-Salem
Regional Office (WSRO). This plan shall be revised with the new WSRO phone number, (336)-776-
9800. Noted. See attached O&M Plan
4. The procedures for sampling and monitoring submitted Operation and Maintenance (O&M) Plan does
not fit all of the criteria listed in 15A NCAC 02T .1110(a)(5). This rule states that the O&M plan shall:
a. Detail procedures for sampling and monitoring to ensure that the program stays in compliance with
this Section and each issued permit. Noted. See attached O&M Plan
The O&M plan shall be revised to include the procedures for sampling and monitoring that are done
to demonstrate compliance for each residuals source. This should include, but is not limited to,
hazardous waste determinations, metals determinations, pathogen and vector attraction reduction
requirements, and methane gas concentration monitoring. Noted. See attached O&M Plan
5. The submitted Operation and Maintenance (O&M) Plan does detail the procedures for post -closure care
management 15A NCAC 02T .1110(a)(6). The revised O&M plan shall include applicable parts of the
management practices for surface disposal unit closure listed in 15A NCAC 02T .1109(d)(3). This rule
states the following:
3. Following active use, surface disposal units shall be closed. Permits for surface disposal units shall
be maintained for three years following successful closure. Requests for approval of closure plans
shall be submitted to the Division at least 180 days prior to the date that a surface disposal unit is
to be closed and shall include the following information:
A. how the surface disposal unit will be closed;
B. a discussion of how the leachate collection system will be operated and maintained, if
applicable;
C. a description of the system used to monitor the air for methane gas in the air in any structures
within the surface disposal unit boundary and at the property line of the surface disposal unit, if
applicable;
D. a discussion of how public access to the surface disposal unit will be restricted; and
E. proof that the deed for the surface disposal unit property has been amended to provide
permanent written notification to subsequent owners of the property that the property was used
for the purposes of operating a surface disposal unit.
Noted. See attached O&M Plan for closure procedure plan.
C. Groundwater Monitoring Plan r15A NCAC 02T .010S(c)]:
The Winston-Salem Regional Office has expressed concerns about the quality and integrity of the clay
liner of the surface disposal unit. 15A NCAC 02L .0107(k) requires that permits be written to protect the
quality and groundwater at the compliance boundary, and that necessary groundwater quality
monitoring shall be conducted within the compliance boundary to evaluate the impact of the waste
disposal unit. Due to concerns about the liner of the surface disposal unit (SU), the age of the SDU, and
the proximity of the SDU to surface waters and floodplain areas, the Division of Water Resources
Central and Winston-Salem Regional offices both agree that groundwater monitoring is warranted at
this facility.
The Division will request that the Permittee provide a groundwater monitoring plan to assess the effect
of the SDU's operation and the surrounding groundwater as a condition in the new permit (i.e., this does
not have to be submitted with response to the rest of this letter). This plan shall include a site map
which contains potential monitoring well locations as well as clear and accurate delineation of the
compliance and review boundary. Please work alongside Patrick Mitchell of the Winston-Salem
Regional office for guidance.
Noted. The Town of Ramseur is aware of the WSRO concerns. The Wooten Company has
reached out to Patrick Mitchell and will discuss with the Town their options to resolve this
concern. The Town will either provide a preliminary plan to Patrick Mitchell's office for testing
the downstream gradient groundwater for 02L parameters or contest the requirement once the
draft permit is received.

OPERATIONAL FUNCTIONS
Description of Wastewater Treatment Plant and Sludge Processes
The Surface Disposal Permit allows disposal of the biosolids from the Town's wastewater
treatment plant and sludge generated by the Town's water treatment plant to the ten acre lagoon.
Following are the treatment units included in the biosolids unit:
Description
Purpose
Return Sludge Pump (2 submersible sludge
pumps)
convey the solids to the sludge holding tank
Sludge holding Tank, 10,000 gallons
Slu a and lime is mixed for stablization
Lime Silo, 25 ton
Storage for lime
Gravity feed line, 200 feet
Convey treated solids from sludge holding
tank to sludge lagoon
10 acre lagoon
Final disposal of treated sludge
Following are process descriptions for both the wastewater treatment plant and the water treatment
plant.
The Town of Ramseur Wastewater Treatment Facility is a 0.480 MGD design capacity facility
treating wastewater from residential and commercial users. The unit treatment processes include
Page 1 of 12
an extended aeration, activated sludge basin, secondary clarification and a polishing pond followed
by chlorination and dechlorination. Excess biological sludge from the treatment process is lime
stabilized and piped by gravity feed to an approved, onsite, ten acre sludge storage lagoon.
The Town of Ramseur Water Treatment Facility is a 1.0 MGD design conventional water treatment
plant. Raw water is gravity feed from Sandy Creek into the sedimentation basins where chemicals
are introduced for taste and odor control, pH adjustment, flocculation/coagulation followed by
filtration, pH adjustment, and chlorination. The treated water is stored in an on -site clearwell
storage tank. Water is then transferred on demand to elevated storage tanks and to the customers
on the system. The solids collected in the sedimentation basin are pumped to a clarifier where the
clarified water is discharged to Sandy Creek. The solids collected in the clarifier from the
sedimentation basin and back washing the filters are pumped to sand drying beds for dewatering
and transport to the surface disposal lagoon at the wastewater treatment plant.

SAFETY & CONTROL OF ACCESS TO SITES
The surface disposal lagoon is located on property owned by the Town of Ramseur. Entrance to
the property is controlled by a private entrance gate and fencing around the property boundary.
SPILL CONTROL & RESPONSE MEASURES
Sludge generated by the Ramseur wastewater treatment is pumped from the clarifier to a 10,000
gallon sludge holding tank. Lime stabilization is completed in the holding tank and gravity
flowed to a 10 acre sludge lagoon. The potential of a spill is restricted to the sludge holding
tank. Personnel is on -site when this tank is being filled and will follow the spill control plan
should a spill occur.
The Town of Ramseur uses a sludge hauling company to transport the sludge from the water
treatment plant to the surface disposal lagoon at the wastewater treatment plant. The Town will
ensure that the sludge hauling company has a Spill Prevention Control and Countermeasure
(SPCC) Plan and is located in the sludge hauling vehicle. The Plan will include, at a minimum:
a) Emergency Response Procedures addressing control, containment, and remediation
b) Cleanup Procedures
c) Notification Procedures
d) Emergency Contact Information
A copy of the SPCCs is included in Attachment I.
INSPECTION & RECORDKEEPING PLAN
The Town of Ramseur will incorporate the following activities and inspections to ensure
compliance with the Permit:

Spill Prevention measures are critical to preventing spills which can harm the environment, aquatic
life, and humans. Spill Prevention measures such as vehicle and equipment inspections, reviewing
Standard Operating Procedures, and ensuring personnel are properly trained should be completed
prior to transporting sludge to the wastewater treatment plant.
IN THE UNLIKELY EVENT OF A SPILL. THE FOLLOWING ACTIONS SHALL BE
TAKEN IMMEDIATELY:
1. MANAGEMENT OF SPILL ACTIVITIES:
The top priority when responding to spills is to stop it as soon as possible. Stopping the flow is the quickest
way to prevent spills from entering surface waters, posing threat to human health and environment. The
Contract Sludge Hauler shall take immediate charge and initiate assessment and clean-up activities. The
Contract Sludge Hauler labor and equipment is to be utilized. In the event additional labor and equipment is
required, assistance may be requested from the Town of Ramseur, the NC Department of Transportation, and
other private contractors as necessary.
2. HALT THE SOURCE OF THE SPILL:
Such as a ruptured container or damaged transport unit.
3. CONTAIN THE SPILL:
Form a barrier using spill containment materials located at the Ramseur Water and Wastewater Treatment
Plants. In addition, sufficient quantities of straw shall be used for such purposes. Earthen barriers may be
constructed to augment the spill containment material and/or straw bale containment area of the spill. The
Contract Hauler or the person in charge on the spill site will advise the clean-up personnel where to get the
spill containment materials, straw, lime, and other items necessary to complete the clean-up operation, i.e.,
local farmers, farm supply centers, nurseries, etc.
4. CLEAN-UP:
Employ front-end loaders, vacuum equipment, sludge application vehicles, and/or local septic tank service to
remove as much of the spilled material as possible. Straw and/or sand should be scattered in the spill area to
soak up the remaining material. The straw- and sand -soaked material will be collected and removed to a
disposal area approved by representatives of the state regulatory agency.
5. FINAL CLEAN-UP:
Employ rotary brush sweeper if needed, and apply lime to the spill area upon the approval of the clean-up
efforts by the state regulatory representative. If the event occurs on private property, the clean-up will be
completed to the satisfaction of the property owner and state regulatory representatives. The ultimate goal
will be to restore the spill area to its original condition if possible.
6. NOTIFICATION:
As soon as possible after the spill occurs, the Contract Hauler will notify the Ramseur Water Treatment Plant
and they will then be responsible for notifying the appropriate agencies.
7. REPORTING:
The Town of Ramseur will notify the NCDENR -Winston Salem Regional Office by telephone (336-771-
4631) as soon as possible, but not more than 24 hours after, or on the next working day following the
occurrence. For after-hours reporting the Division's emergency number shall be called to report all
incidences (800-662-7956 or 800-858-0368 or 919-733-3300). The Town of Ramseur will file a written
report to the Winston Salem Regional Office within 5 days of the occurrence.
8. SPILL ESTIMATION METHODS
Accurate spill estimation is critical for reporting purposes. The following types of estimates can be used:
Eyeball Estimate
To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket
contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break
the standing water into barrels and then multiply by 50 gallons. This method is useful for contained
spills up to approximately 200 gallons.
Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The
shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions
are used to calculate the area of the spills and the depth is used to calculate the volume.
Step 1 Sketch the shape of the contained sewage.
Step 2 Measure or pace off the dimensions.
Step 3 Measure the depth at several locations and select an average.
Step 4 Convert the dimensions, including depth, to feet.
Step 5 Calculate the area in square feet using the following formulas:
Rectangle: Area = length (feet) x width (feet)
Circle: Area = radius (feet) x radius (feet) x 3.14
Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in
cubic feet.
Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons
SPILL PREVENTION AND RESPONSE PLAN

Spill Prevention measures are critical to preventing spills which can harm the environment, aquatic
life, and humans. The potential of a spill during the sludge disposal process is restricted to the
sludge holding tank. As preventative measures, the sludge holding tank is routinely inspected for
leaks. In addition, personnel will be on -site when this tank is being filled to observe and monitor
the operation.
IN THE UNLIKELY EVENT OF A SPILL, THE FOLLOWING ACTIONS SHALL BE
TAKEN IMMEDIATELY:
1. MANAGEMENT OF SPILL ACTIVITIES:
The top priority when responding to spills is to stop it as soon as possible. Stopping the flow is the quickest
way to prevent spills from entering surface waters, posing threat to human health and environment. The
wastewater treatment plant staff shall take immediate charge and initiate assessment and clean-up activities.
In the event additional labor and equipment is required, assistance may be requested from the Town of
Ramseur and other private contractors as necessary.
2. HALT THE SOURCE OF THE SPILL:
Such as a ruptured container or damaged transport unit.
3. CONTAIN THE SPILL:
Form a barrier using spill containment materials located at the Ramseur Wastewater Treatment Plant. In
addition, sufficient quantities of straw shall be used for such purposes. Earthen barriers may be constructed
to augment the spill containment material and/or straw bale containment area of the spill. The WWTP ORC
or the person in charge on the spill site will advise the clean-up personnel where to get the spill containment
materials, straw, lime, and other items necessary to complete the clean-up operation, i.e., local farmers, farm
supply centers, nurseries, etc.
4. CLEAN-UP:
Employ front-end loaders, vacuum equipment, sludge application vehicles, and/or local septic tank service to
remove as much of the spilled material as possible. Straw and/or sand should be scattered in the spill area to
soak up the remaining material. The straw- and sand -soaked material will be collected and removed to a
disposal area approved by representatives of the state regulatory agency.
5. NOTIFICATION:
As soon as possible after the spill occurs, the WWTP ORC will notify the Town of Ramseur and they will
then be responsible for notifying the appropriate agencies.
6. REPORTING:
The Town of Ramseur will notify the NCEQ/DWR - Winston Salem Regional Office by telephone (336-776-
9800) as soon as possible, but not more than 24 hours after, or on the next working day following the
occurrence. For after-hours reporting the Division's emergency number shall be called to report all
incidences (800-662-7956 or 800-858-0368 or 919-733-3300). The Town of Ramseur will file a written
report to the Winston Salem Regional Office within 5 days of the occurrence.
7. SPILL ESTIMATION METHODS
Accurate spill estimation is critical for reporting purposes. The following types of estimates can be used:
Eyeball Estimate
To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket
contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break
the standing water into barrels and then multiply by 50 gallons. This method is useful for contained
spills up to approximately 200 gallons.
Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The
shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions
are used to calculate the area of the spills and the depth is used to calculate the volume.
Step 1
Sketch the shape of the contained sewage.
Step 2
Measure or pace off the dimensions.
Step 3
Measure the depth at several locations and select an average.
Step 4
Convert the dimensions, including depth, to feet.
Step 5
Calculate the area in square feet using the following formulas:
Rectangle: Area = length (feet) x width (feet)
Circle: Area = radius (feet) x radius (feet) x 3.14
Triangle: Area = base (feet) x height (feet) x 0.5
Step 6
Multiply the area (square feet) times the depth (in feet) to obtain the volume in
cubic feet.
Step 7
Multiply the volume in cubic feet by 7.5 to convert it to gallons
